Answer:
8
Step-by-step explanation:
5-(-3)=8
|8|=8
To find the area of a prism, you calculate the area of the cross-section and multiply that number by the length. The cross-section of this prism is a trapezium, and the formula for this is
![\frac{a+b}{2}h](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%2Bb%7D%7B2%7Dh)
.
Insert your given numbers to find out the area of this prism's cross-section:
![\frac{3+12}{2}12=90](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%2B12%7D%7B2%7D12%3D90)
Now, multiply 90 by the length, 10cm, to find out the volume of the prism;
90×10=900cm³
Therefore, your answer id the third option.
